My Dearest Sister

Work Text:

Tanjirou loves his sister, Nezuko
He made a vow that he will protect his little sister, no matter what
Even when death sets them apart

As the summer wind hits through the bustling streets of Tokyo, as the orange color started to colored the blue sky,Tanjirou walked passed all the people, not worrying about his rather weird appearance
Right in front of him, stood a girl wearing a green and black checkered hoodie. Her backpack swings along her body movements. Her long black and orange hair sways with the wind
Tanjirou reached his arm, touching the girl's back
The girls didn't even flinched, she just kept walking to a bus station, before Tanjirou managed to catch up, the girl already jumped into the bus, which leaves shortly after
Tanjirou sighed and turned his heel to the opposite direction, running as he chase the thing called "bus"
He panted as his breath getting shorter and shorter
He ran pass the people, crashing into them without them noticing

After a short and tiring run, The bus stopped and the girl stepped out. Tanjirou took a moment to catch his breath and began walking the same pace as the girl
The girl entered a small apartment, and Tanjirou followed

The girl sighed and lock the door behind her, walking pasa Tanjirou as if she is walking through empty air.She toss her backpack randomly. Her sharp pink orbs took a glimpse at the sword hanging on the wall
"I'm back, big brother"
She murmured as she steps further into the apartment, entering her room
Tanjirou smiled at her words
"Welcome back, Nezuko"
Tanjirou said with a smile, even though Nezuko couldn't see it

Tanjirou walked around his sister's apartment. Checking if everything is in place
'Nezuko sure does knows how to clean'
Tanjirou thinks to himself. If Zenitsu is here with him, he is sure that Zenitsu would ask his sister in marriage
But sadly, Zenitsu isn't here. He's not even in this world anymore
Tanjirou turned his focus to his nichirin sword, now hanging at the wall of Nezuko's living room
He touched the sword with his pale fingers, cold
The sword is cold, not how it used to be. Dust began to collect on top of it
Tanjirou blowed the dust away, but the dust stay stills
Tanjirou then chuckled, realizing that he couldn't make any contact with the world anymore

He then trotted to the balcony, walked through the glass door easily and sits on the iron railings
How long has it been? He thought to himself
If he recalled it correctly, it has been a bit over 60 years by now
Tanjirou's burgundy eyes looked at the streets under him, the night have already came. Usually he would step outside, look for some demons, but he couldn't do it anymore

After the defeat of Kibutsuji, there's no way demons are still In this world. Only Nezuko. And Nezuko is a nice demon
"I wish I could talk to her.."
Tanjirou commented
But he can't. The last time he talked to his sister is a bit over 60 years ago. When his sister cried and held his fragile fingers, stroking his face that is covered by wrinkles
And the last thing he knew is that his sister promised  to keep searching the cure he's been searching for his life

Enjoying the night breeze, Tanjirou let memories flows In his mind
After Kibutsuji's death, the demon slayer corps are disbanded
He and Nezuko kept searching for the cure. They went place to places, spending nights in the forest, even crossed steep canyon
At the end, he didn't find the cure. His body has aged, he couldn't even walked anymore
Before closing his eyes, Tanjirou, with all of the power he have left, promised to Nezuko to protect her, even if death set them apart

Tanjirou sighed as the busy streets under him began to shine with colorful lights. The world has changed, he thought to himself
He wish he could enjoy the world, unfortunately he can't. Now here he is, living as a spirit, taking form of his 15 years old body, following his little sister everywhere, keeping his promise to protect her

As he entered the apartment from the balcony, a soft snarl is heard from the bedroom. Tanjirou cracked a small smile as he saw his beloved sister fell asleep at the bed, without bothering to change clothes first
Tanjirou brushed Nezuko's face slowly, Carresing the Hanafuda earrings his sister wore. It used to be his, but his sister took it as a memento. Tanjirou grabbed the blanked folded at the foot of the bed before covering Nezuko in it's warmth. Her checkered hoodie ruffles as she shifted her position for better sleep. Tanjirou traced the sewing on it, amazed on how Nezuko can turn his Haori into a such clothing
Tanjirou gripped his own Haori, the same checkered pattern as her sister's hoodie
"You've sure have grown, Nezuko"
Tanjirou said as he fixed the blanked. Suddenly he heard Nezuko muttered in her sleep

"Big brother... "
Tanjirou startled by the sudden motion
Nezuko shuffled her head's position on the pillow, gripping the edge
"Brother... I miss you.. . "
And Tanjirou felt his eyes getting wet. With a soft move, he patted Nezuko's hair softly
"I miss you too, Nezuko"
Tanjirou answered,and he can see Nezuko smiles shortly

He then took light steps and headed to her desk not far from her bed
On top of it there's a lot of books and a device called "laptop"
Tanjirou remembered that Nezuko entered a pharmaceutical school nearby, and he is sure he isn't wrong when he took a glimpse of the books
"Blending with other humans.. That must be hard. Sorry, Nezuko. You have to get through all of it without me"
Tanjirou thinks to himself as he took a piece of paper that is lying on the desk, it's one of Nezuko's "letters"

He's been following Nezuko for 60 years plus. Everytime Nezuko finished her routine or feels stressed and lonely, she would wrote a letter for him, despite the letters just got stored at the drawer and it basically re tells what has happened on that day. He saw Nezuko moved from place to places, he saw Nezuko hid her claws and fangs In order not to draw attention, he saw Nezuko holding herself back from the smell of human blood, he saw Nezuko talked to other humans like she is one of them
It's must be hard, to fake yourself, That's what Tanjirou thought and seeing his beloved sister do it makes his heart pounded in pain. If only he is there to support her

He turned his attention to the letter. It seems that Nezuko forgot to put it in an envelope

Tanjirou smiled as he put the letter back, he pulled out something his pocket
It's a small teddy bear, it's Nezuko's favorite. The teddy bear wore the same Kimono Nezuko used to wear during their demon hunting days
He puts the teddy bear near the letter, before turning to Nezuko's sleeping body
Tanjirou pressed his lips to Nezuko's forehead with much love like how he used to do

"Sleep well, Nezuko"










Nezuko woke up as the alarm of her phone beeps. She ruffled her hair randomly, kinda regreted the fact that he hasn't took any shower or food since last night. She is just so tired that she even fell asleep right before dinner
Nezuko stroked the Hanafuda earrings on her ears
"Good morning, big brother"
She said as she get on his feet, her half opened eyes completely wide opened as she saw something familiar on her desk

Her old teddy bear is there with a small note
"I promise I will protect you"
The simple words made Nezuko's eyes waters
She cried instantly, hugging the teddy bear to her chest
"Big brother... "
And suddenly she felt a warm hand hugged her from behind, indulging her in such warmth
And she can saw some burgundy locks from her back, unsure if it's her imagination or not

"Don't worry Nezuko. Big brother is here. No need to cry"
